In ICSE Physics Class 8 Solutions Light energy is a kind of kinetic energy capable of making light types visible to the eyes of humans. Light is defined by hot objects like lasers, bulbs, and the sun as a form of electromagnetic radiation. Get the ICSE Physics Class 8 Solutions on the Extramarks website.
Light contains photons that are minute energy packets. When the atoms of an object are heated up, photons are produced and this is how photons are produced. The electrons find heat excitement and gain extra energy. The energy is released in the form of a photon, and as the substance gets hotter, more photons come out.
In ICSE Class 8 Physics Solutions When it travels, light travels in the form of a wave. No matter, however, is essential for the transportation of energy to travel. That's why light can travel through space without air. Sound waves are not the case because they have to travel through solids, liquids or gas. Light energy is very fast, travelling faster than anything else. The speed of light is equivalent to 186,282 miles per second. Get the ICSE Class 8 Physics Solutions only on Extramarks.
A lot of electromagnetic radiation is emitted by the sun. Only a fraction of this energy known as' visible light' can be seen by humans. The mode of travelling solar energy is expressed as waves. By measuring its wavelength and distance between consecutive points of a wave (from crest to crest and trough to trough) scientists can calculate the amount of energy a wave has.

Visible light is one of many types of electromagnetic radiation emitted by the sun. The electromagnetic spectrum is defined as the spectrum of all possible radiation frequencies. It shows various types of rising electromagnetic radiation from the sun, including ultraviolet rays and X-rays. Within the electromagnetic spectrum, different types of radiant energy from the sun have been differentiated and the difference between wavelengths points to the amount of energy they carry. ICSE Solutions for Class 8 Physics are available on the Extramarks app.
Infrared waves are a type of heat-spending electromagnetic energy. Have you ever had some delicious grill hot dogs and hamburgers? The burning charcoal puts off the infrared energy that helped the burgers and dogs to cook. Students can get the ICSE Solutions for Class 8 Physics on the Extramarks website.
